[a all whom. it may concern:

Be it known that I, SAMUEL E. CARLIN, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Type-WVriting Machines, of which the following is a specification.

This invention relates to a mechanism for tabulating and feeding the typewriter carriage, so as to bring any desired point of a written line opposite to the printing point of the typewriter, and is a division of my application No. 504,595, filed June 26, 1909.

A feature of this invention is the provision of mechanism to enable the spacing or traversing of the carriage definite predetcrmined distances and selectively either to the right or to the left. To accomplish this feature. there are provided two series of tabulating keys, one for spacing the carriage to the right and the other for spacing the carriage to the left. These keys control the connection of mutilated gears to a source of power, whereby these mutilated gears when so connected may drive gearing connected to traverse the carriage either to the right or to the left according to the particular series to which the key actuated belongs. The mutilated gears have varying numbers of teeth starting with one for one letterspace movement of the carriage, and ascending in regular order by an increment of one tooth corresponding to the several tabulating keys from one to the highest number, and in this instance, 5. That is to say, the mutilated gear corresponding to the 2 key has two teeth, and to the 3 key, three teeth, and so on.

A. further feature of this invention is the provision of traversing mechanism for the carriage, to enable the movement of the carriage any desired undetermined distance in a continuous manner and either to the right or to the left. This end is accomplished by the provision of two clutches, which are normally ineffective but can be made effective to connect the aforesaid source of power in driving relation with the carriage. By the connection' of one clutch. the carriage will be traversed to the left. and by the connection of the other clutch, it will be traversed to the right. So long as either one of the clutches is held in operation, the carriage will be moved by the source of power and will stop only when the clutch is released.

A further feature of this invention is the provision of means to interrupt the control of the movement of the carriage from the source of power. This may be accomplished by the provision of a clutch in the driving train connecting the source of power to the carriage, which may be thrown out of operation temporarily by the depression of a special key provided adjacent the other keys of the keyboard. A still further feature of this invention is the provision of means to enable the normal step-by-step letter-feeding movement of the carriage to be accomplished from the source of power at the striking ofany alphabet key. This is accomplished by the provision of a universal bar, which at the operation of any alphabet key, enables the connection of one of the single-tooth mutilated gears with the source of power to provide a single letter-spacing movement of the carriage.

Other features and advantages will hereinafter appear.

Fig. 18 is a detail perspective view of one of the trippers. Fig. 19 is a vertical section through the connection of one of the trippers to its actuating link. Fig. 20 is a detail perspective view of one of the locking rings or rollers.

Numeral keys 1 and alphabet keys 9. depress key levers (Fig. 5). to actuate through the intermediary of linkages 4, type bars iswinging them up rearwardlyagainst the front side of a platen (i, mounted to rotate on a carriage T which slides right and left in guides 8. The carriage 7 is provided, at its rear. with a rack 9. by means of which it may be traversed either to the right or left.

Engaging with the rack 9 to drive the same, there is provided a pinion 10, mounted on a shaft 11 (Figs. 11 and 12). The shaft 11 has secured thereto. a clutch member 12. which is normally engaged by a slidable clutch f). to connect the shaft 11 in driven relation with a shaft 14 on which the clutch 13 is splined. It will he noted in passing that the clutch member 1'. is also provided with a l"ltlll. ratchet wheel 15. en gage-able by a spring-pressed d tent 16 (Fig. 14;). which has a number of teeth such that the detent 16 will flCClUfltGlY determine the position of the. carriage for each letter space.

The shaft 14 is provided. at its rear end (Figs. 11, 4 and 5). with a bevel gear 17 meshing with a companion bevel gear 18 on a vertical shaft 19, which is driven from a shaft 20 by means of a pair of companion gears 21 and 22 secured, respectively, to the shafts 19 and 20. 520, at its forward end, there is provided a bevel gear 23 (Figs. 3and 1), which meshes with a pair of bevel gears 24 and 25, facing in opposite directions and secured, respectively. on shafts 26 and 27. It will thus be seen that when the shaft 26 is rotated to drive the shaft 11 through the intermediary of the shafts 20, 19, 14 and the connected caring, the pinion 10 will be driven in one direction to traverse the carriage 7 in one direction, but that when the shaft 27 is driving. the pinion 10 will be driven in the 0pposite direction to traverse the carriage in the opposite direction. As the gearing is arranged when the shaft 26 is rotated, the carriage 7 will be traversed toward the left in a letter-feeding direction, and when the shaft 27 does the driving, the carriage 7 will he traversed to the right in a return direction.

The shafts '26 and 27 receive their drive from a common source of power indicated by an electric motor 28 (Fig. 1). trio motor 98 is provided which meshes with ha ft 31. so that the rotated. The shafts with a pinion 29 a gear 30 secured to a shaft 31 is continuously 26 and 27 receive their 4 rotation from the shaft 31 in a number of ways. The first way to he considered will be whereby the shafts may be driven continuously an undetermined amount so as to space the carriage an undetermined amount either to the right or to the left. To accomplish this, the shares-3,1 has secured thereto, a pair of gears 32 and 33, which mesh, respectively, with gears 34 and 35, mounted respectively and loosely on the shafts 26 and 27. It will thus be seen that the gears 34 and 35 are continuously rotated but that they are not normally connected to their respective shafts 26 and 27. If, then, it is desired to traverse the carriage to the left, that is. to drive the shaft 26. it isnecessarv to connect the gear 34 positively to the shaft 26. To accomplish this, the gear 34 is provided with a toothed clutch 36, into engagement with which may be brought a corresponding clutch 37 splined on the shaft 26. so as to be fixed against rotation relative thereto. To move the clutch into engagement with the clutch 36, there is provided a control shifting lever 38, which is pivotallv mounted intermediate its ends. a at 39. and engages in an annular groove 40 on the clutch 37., The lever 38, however. is normally held in such a position that the clutch 37 will be disengaged from the clutch 36 bv a spring 41. In'order then to traverse the carriage to the left an undetermined distance, the lever .38 must be swung about its pivot against the tension of Also secured on the shaft' This electhe spring 41, so as to bring the teeth of the clutch 37 into mesh with the teeth of the clutch 36, when there will be effected a continuous drive from the motor 28 to the pinion 10, so that the carriage will e traversed to the left until the operators hand is disengaged from the control lever. The spring 41 then will automatically break the connection, permitting the detent 16 to lock the carriage in whatever position it has been adjusted to and exactly corresponding to a letter space. Similarly the gear 35 may be locked to the shaft 27 by interlocking clutch members 42 and 43, the latter of which is splined on the shaft 27 and shiftable by a control shifting lever 44. In this instance also, the lever 44 is held by a spring 45 in such a position that the clutch elements 42 and 43 will normally'be disengaged from each other. It is, of course, understood that the clutch lever 44 controls the shifting of the carriage to the right an undetermined distance, which depends on the period of time which the operator holds the clutch elements 42 and 43 in engagement with each other against the tension of the spring 45. In addition to undetermined movements of the carriage, provision is made for accurately predetermined movements of the carriage to the right or left. For this purpose, the shaft 31 is provided with two series 46 and 47 of mutilated gears 48. The series 46 is used to space the carriage toward the left and the series 47 is used to space the carriage toward the right. In this instance there are five mutilated gears in each series and each gear in a series is different from any other gear. That is to say, there is in each series a mutilated gear having one tooth; another having two teeth; still another having three teeth, and so on, increasing by as many increments as there are gears, up to the number of spaces which it may be desired to move the carriage at one stroke of the key, which in this instance is shown to be live. The mutilated gears 48 (Figs. 4, 7 and'lO) are loosely mounted on the shaft 31, so that they are not normally driven thereby. Each one, however, can be individually clutched to the shaft 31, so as to be driven thereby. \Vhen so clutched to the shaft, it will rotate therewith so as to bring the teeth thereof in mesh with the teeth of full gears 49 secured on the shafts 26 and 27. There is one of these gears 49 fixed on the shaft 26 for each of the mutilated gears 48 in the series 46. There is likewise one of these gears 49 secured on the shaft 27 for each of the mutilated gears 48 in the Series 47. It will thus be seen that when a mutilated gear is clutched in driven relation with the shaft 31, it will drive the opposite gear 49 an amount corresponding to the number of teeth which it has. That is to say, if a one-tooth mutilated gear 48 is clutched to the shaft 31, it will rotate the gear 49 with which it meshes. one single step or tooth-space; correspondingly, a. twotooth mutilated gear will rotate the mesh ing gear 49, two steps or tooth-spaces, and so on. In this way, if it is desired to space the carriage definitely one, two, three, four or five spaces to the left, the corresponding mutilated gear in the series 46 will be clutched to the shaft 31, so as to drive the shaft 26 a corresponding amount, whereby the pinion 10 will be rotated in such a direction and such an amount as to space the carriage 7 to the left the required distance. If it is desired to space the carriage t0 the right a definite distance, one of the mutilated gears in the series 47 will be clutched to the shaft 31 to drive the shaft 27.

In order to connect any one of the mutilated gears 48 so that it will rotate with the shaft 31, there is provided adjacent each of these mutilated gears, a clutch star wheel 50, which is secured to the shaft 31, thereby always rotating with the shaft. Pivotally mounted on each of the mutilated gears 48, there is provided a clutching pawl 51, which is normally urged by a spring 52, so that it tends to engage the star wheel 50 for the purpose of clutching the corresponding mutilated gear 48 to the shaft 31. This clutching engagement, however, is normally pre vented by disconnecting trippers or triggers 53, of which there is one for each mutilated gear and the nose of which lies in the path of a lug or projection 54 on the associated pawl 51. v The position and relation of the tripper or trigger 53 to the pawl 51, is such that any tendency of the mutilated gear 48 to rotate with the shaft 31, will cause the tripper or trigger 53 to swing the pawl 51 about its pivot against the tension of the spring 52, so as to disconnect the clutching pawl 51 from the clutching star wheel 50. If, however. a disconnecting tripper or trig ger 53 should be swung about its pivot 55 to such a position that the nose of the tripper or trigger would be moved away from the lug 54, then the spring 52 would be permitted to act, forcing the pawl 51 into clutching engagement with the star wheel 50, so that its associated mutilated gear 48 would be connected in driven relation with the shaft 31. Inasmuch as the trippers or triggers 53 are normally held by springs 56 in such a position that the toes thereof will engage the lugs 54, it is necessary to forcibly rock the trippers or triggers against the tension of the springs. To accomplish this, there is provided for each mutilated gear, a tabulating key 57, which is pivotally mounted as at 58 and connected to the associated tripper or trigger by a link 59. The keys 57 are arranged in two series 60 and (i1, corresponding to the spacing of the carriage to the left and right, respectively. These keys are numbered from 1 to 5 in each series, according to the number of teeth on the associated mutilated gears and according to the number of letter spaces which they will.

space the carriage when struck. In order that the trippers or triggers 53 will come into the path of the lugs 51, so as to permit solely one rotation of a mutilated'gear with the shaft 31 for a depression of the corresponding key 57, there is provided positive means for rocking the trippers or triggers 53 back to their effective position.

Connected to each of the mutilated gears 48, there is provided a cam 62, which will rotate with the associated gear so that after the teeth'thereon have performed their work, this cam will engage an arm 63 in each instance, so as to rock a shaft 61. That is to say, when any one of the mutilated gears is connected to the shaft 31, so as to rotate therewith, one of the arms (33 will be actuated to rock the shaft 61. Secured on the shaft 64 are also provided two pairs of arms 65, each pair being connected by a transverse bar 66, which is universal to all of. the trippers or triggers 53 in a set. \Vhen the shaft 64 s rocked, both these bars 66 will en 'age the tail end of said triggers or trippers 53, so as to rock them about their pivots, and thus insure the bringing of the toes thereof into the path of the corresponding lugs 54 on the pawls :71. This positively insures the stopping of the mutilated gears after a single rotation for each depression of the associated tabulating key 57. To prevent overthrow of each of the mutilated gears, there .is secured thereto, as will be seen by reference to Fig. 15, a disk 90, having a notch 91 therein which is "engaged by a dog or gletent 92 when the associatedmutilated gear fin ishes its movement by being disconnected from the shaft 31/ The dogs or detents 92 are normally held in a position to engage the notches by individual springs 93. The rock shaft 64 is also used to prevent overthrow of the shafts 26 and 27. For this purpose. these shafts are'each provided at their left and right ends, respectively, with a detent wheel 67, engaged by a detent 68 (Fig. 8) loosely mounted on the rock shaft 61. On each end of the rock shaft 64, there is provided an arm 69, with a projecting pin 70, which overlies the associated detent 68, so as to force it into locking engagement with the associated detent wheel 67 on the corresponding one of the shafts 26 and 27. Each detent 68 is locked in its in and out positions by a spring-pressed pawl 71, which engages either one apair of notches 7 2 on anarm 73 secured to and forming a part of the detent 68 in each case.

It is, of course, necessary to obtain a spec ing of the carriage in the normal letterfeedingidirection at the actuation of any of the character keys. The numeral keys space 'this guideway,

in a manner not shown in this application but described and claimed in my above-mentioned application, No. 504,595. In the case of the other keys, such as the alphabet keys 2, there is provided a universal bar 74, which underlies all of the levers 3 of these keys, so as to be depressed when any one of these keys is depressed. This universal bar connects arms 75, which are mounted to rock on the shaft 58. One of the arms 75 extends beyond its pivot point, as at 76, where it is connected-by a link 77 to an offset 78 0f the particular tripper or trigger 53 which cooperates with the single-tooth mutilated gear 48 in the series of mutilated gears 46. That is to say, it cooperates with the mutilated gear which will cause a single letterspace movement of the carriage toward the left. It will thus be seen that when any one of the alphabet keys is depressed to strike a character, it will cause a single letter-space movement of the carriage to the left, and the universal bar 74 and the trippers or triggers 53 will be returned to their normal position by one of the springs 56. If for any reason it is desired to render the carriage independent of the controlling mechanism therefor, it will be merely necessary to depress a key 80, to rock a lever 81 about its pivot 82, so as to rock a bell crank shiftin lever 83 through the intermediary of a CQ Ih necting link 84. The shifting lever 83 is forked at its opposite end to engage in an annular groove 85 provided in the clutch 13. This clutch is normally held in engagement with the opposite clutch 12 by a spring but will be thrown out of engagement therewith when the key 80 is depressed. Inasmuch as when the clutch 13 is disengaged from the clutch 12 the drive between the shaft 11 and the shaft 11 will be interrupted, the carriage 7 will remain stationary in spite of the manipulation of any of the parts of the carriage-spacing controlling mechanism. In order that the spacing of the carriage may be definite when any one of the keys 57 is depressed, provision is made whereby the mutilated gear of more than one key cannot be in action at the same time. For this purpose, all of the trippers or triggers 53 with the exception of the one cooperating with the one-tooth mutilated gear of the series -16, are extended at their tail ends to such an e.\'- tent that when they are rocked, these tail ends will pass between a pair of locking rings or rollers 112. These locking rings 112 are loosely mounted in a run-way or guide- Way 118, and the tails of the trippers 53 are arranged in alinement with the slots 111 in so that they can pass up into the same to spread apart the nearest two of these rings. The runway or guideway 113 is blocked at its ends, as at 115, to revent more than a given movement of the rings, so that while there is suflicient space for one tripper 53 to enter between two rings, this will crowd the other rings together, so as to close up the spaces therebetween, preventing the intrusion of any of the other trippers 53. It will thus be seen that by this means, after one tripper is actuated and in its ineffective position, then no other tripper can be actuated until the one in play has re turned to its normal position. Each of the trippers may be'provided with a pair of 'notches 116 and 117, which are engaged by a detent 118 to yieldingly detain the tripper in both of its adjusted positions.

The operation of the device will be readily understood when taken in connection with the above description. If it is desired to traverse the carriage so as to bring any particular point of the work-sheet opposite the printing point of the typewriter, this can be done my manipulating one of the levers or 44, if the distance which it is desired to move the carriage is not exactly known. If the carriage is to be moved to the left, the lever 38 at the left will be manipulated, and if it is to be moved to the right, the lever M at the right will be manipulated. Each lever connects its particular shaft 26 or 37 in driven relation with the motor, so that the carriage will be driven toward the left or right according to which lever is operated. The movement will be continuous just so long as the lever is held against the tension of its spring, so as to maintain the sociated clutch elements in engagement with each other. As soon as the particular lever is released, the drive will be automatically stopped and the carriage accurately locked at some particular letter space by the justifying detent 16. If, on the other hand, it is desired to space the carriage a given amount, as in tabulating, it is merely necessary to press one of the keys 57. If it is desired to space the carriage to the left, one of the keys in the series 60 would be actuated, the particular one being selected according to how many letter spaces it is desired to move the carriage. For example, if it is desired to space the carriage two spaces, the 2 key will be depressed; three spaces, the 3 key will be depressed, and so on. On the other hand, if it is desired to space the carriage toward the right, one of the keys at the right in the series 61 would be depressed, the particular one depending upon the number of spaces required, as in the case of the other series. In the ordinary operation of typewriting, the character keys 2 when struck will automatically cause a connection of the one-tooth mutilated gear in the series 46 to the shaft 31, so as to bring about a single letter-spacing movement of the carriage 7 to the left, that is, in a letter-feeding direction. If for any reason it is desired to disconnect the carriage from control .by the levers 38 and 44 and the keys in the series 60 and 61, it is merely necessary to depress the key 80, when the clutch 13 will be disconnected from the clutch 12, to interrupt the drive between the motor and the pinion. 10 which traverses the carriage.
